Creo view 3.0 M010 hangs while opening multiple drawings

When multiple drawings are opened from multiple sessions and multiple tabs of windchill,creo view hangs with a loading symbol.

Windchill version is 10.2M010. , Creo view lite is 3.0 M010 build15.

No information errors or warnings are seen in the trace logs.

Is there any limit on opening the no. of documents or on the no. of windchill sessions to be used to open drawings in creoview?

Any comments or information shared would be most helpful.

Thanks,

Pavithra.
